Guys quick question. I have a set of zcp's.

I'd like to run
Front: 245/35/19 with ContiSportContact 3
Rear: 265/30/19 with Conti DW's.

Offsets are
9x19 et 31
10x19 et 25

I do not plan on lowering the car, and I have M-sport package, which is regular sport suspension. Also I have a 2010 which is pre-lci.

I know that these tires are less wide then Bridgestone and wider then Falken Fk452's.

I also know that I probably have to a roll on the rears.
However I was hoping to not have to work on the fronts with 245, I know 235 doesn't require any modification.

I do not want to buy new tires, maybe just for the front I have some hankooks in 235.

I have searched extensively, but hope someone who has done this on E92 can chime in.

Thanks guys.

I have seen people make it work:

Stick to the 235/35 and 265/30. That way you will not have to do any suspension modification. Just the roll the fenders in the rear.

Running 245 will require modification?

Good chance they will rub at full lock. I have 235/40/18 on ET20 and they rub ever so slightly in reverse. 245/35/19 on ET31 is larger in every dimension.

245/35 is way too tall for the fronts compared to the rear 265/30. car will drive like shit.

I'm not sure if I understand why they would be too tall? 235 and 245, main difference is the width, and maybe a little height? Please correct me if I'm wrong.

245/35/19 is a half-inch taller in overall diameter than the rear 265/30/19.

245 = width cm
35 = % of width
19 = wheel diameter

I understand that, however my question is comparing 235 and 245 for clearance and fitment up front. The recommended fitment for 19" is 235/35 and 265/30, which means front compared to back is also half inch taller?

235/35/19 = 25.48 in.
265/30/19 = 25.26 in.
0.217 inch difference. better than the 0.49 inch difference with 245/265.

i personally would recommend 225/35 front and 265/30 for your setup.

(i would normally suggest 235/35 and 275/30 but you'll rub in the rears on dips and seems like you dont/wont roll the fenders)

Yeah I don't want to roll if I don't have too, however I do not think I will have a choice. I have been running 235 up front with 265 in rear, and has always handled great with Hankook V12's . I think I will test fit 245, and if it doesn't fit/ handle properly, switch to 235.
